What is the difference between Root account and a normal user account in terms of privilege?

root has full priveledges, normal users don't - they can not instal sfotware globally, or delete system wide data and many other things...

Root account can perform any task where as a normal user account cannot. The root account is the administrator account as in Windows. A normal user account hasn't got the privileges root has for obvious reasons, initially after installing your linux distro you will find a normal user in most cases cannot even install additional software unless the account privileges are changed.

alot of difference, simply put root is god and normal users are everyone else
some things root can do that normal users can't
add normal user accounts
reboot/shutdown the system (although this privelege can i think be given to normal users)
edit the /etc files
see ALL of the normal user's files
kill anybody's tasks, not just his/her own
delete the entire file system by accident
globaly install software for everyone to use
i can count on one hand things that root can't do that normal users can, although i can't really name any of those right now, and the reason those are normal users only is because to do so as root would be to risk torching the whole system because root can delete the entire filesystem and linux won't stop him/her

Thanks for your thoughts
